Review context
These calculated indicators are prompts for checking source data, reporting grain, denominators, and local context. They are not evidence or findings of fraud, misconduct, or an incorrect election outcome.
Average President-vs-down-ballot difference crossed threshold: DEM 10.91%, REP -11.26%.
The average gap between presidential votes and same-party down-ballot votes is large enough to review. Split-ticket voting can explain some gap; this flag identifies areas needing supporting records.
Drop-off outlier count crossed threshold: DEM 17, REP 39, trigger 10.
Enough local result rows have unusually large President-versus-down-ballot differences to pass the outlier-count threshold. This is an advisory review flag, not proof of tampering.
Vote-share correlation crossed threshold: Trump r=0.538, Harris r=0.502.
Bigger local reporting-unit vote totals move with candidate vote share strongly enough to pass the native review threshold. This is an advisory review flag, not proof of tampering.

Verified Voting Verifier data is jurisdiction-level election-administration context. Most rows are counties, but some states report state-level rows and some county rows can summarize mixed tabulation, accessible-device, absentee, poll-book, or other configurations. Treat it as source-linked context, not proof every precinct in a county used one identical setup, and not a turnout or vote-result source.Open source
